You Never Sold to Them — So Why Do the Sanctions Still Reach You?

Because sanctions attach to the channels a transaction passes through, not to the counterparty. Which currency settles it, whose flag the ship flies, who writes the insurance — one connection to the sanctioning state is enough to bring the trade inside.

Four hooks — and none of them is about who you sell to

Hook	What it attaches to	Can a firm choose not to use it?	What removing it costs
Settlement currencyThe broadest hook	Any trade priced in that state’s currency. A sale entirely between third countries falls inside US jurisdiction once it is priced in dollars.	In theory yes, in practice rarely. Commodity quotes, hedging instruments, and long-term contracts are largely dollar-denominated.	Carrying the currency risk yourself, a smaller pool of counterparties, and prices that no longer compare. Switching currency replaces the entire pricing benchmark.
The clearing system	Every payment that passes through its financial institutions. An intermediary bank inside the country is enough, wherever the parties sit.	Alternative rails exist with fewer participants and higher cost — and using them may itself be read as evasion.	Slower settlement and heavier assurances from counterparties. Banks usually withdraw before regulators act: it is their own licence at stake.
Technology content	A product containing that state’s technology. Design, manufacture, and sale can all happen abroad and still fall inside.	Redesign is possible once you know where the content is — and it sits three or four tiers deep, while most firms see only the first.	Redesign, requalification, recertification. The price here is usually measured in years rather than money.
Participation by nationals	A national of that state took part in the decision or approval. A meeting or a signature can be the link.	Specific people can be walled off from specific decisions, but only with a compartmented process — and most decision records were not designed that way.	Higher management overhead, and an arrangement that may itself be questioned as deliberate circumvention. This is the hardest hook to prove you handled correctly.

Reading sanctions as “do not deal with sanctioned parties” misses all four hooks, because none of them attaches to the counterparty. They attach to the channels a transaction passes through: currency, clearing, technology, people.

The middle column is the point. A firm can choose its customers; it cannot easily choose not to use dollars, not to use the main clearing system, not to use parts containing controlled technology. The hooks work because they sit on infrastructure, and there is no second set of infrastructure. Which is why the compliance perimeter follows the hooks rather than the address of the office.

How do sanctions differ from “you may not trade with country X”?

Comprehensive embargoes exist but are the exception. Most sanctions target named people, named entities, particular goods, or particular conduct — not a whole country.

That difference shapes the compliance work. An embargo is a question about nationality; ordinary sanctions are questions about who the counterparty is, what the goods are, how the money moves, and how the cargo travels. The same shipment can be lawful to one buyer and unlawful to another, and the product is not what changed.

So “we do not do business with that country” answers none of the questions that actually arise. What has to be answered is whether any step in the transaction touches one of the hooks.

What exactly is a “hook”?

A hook is the basis on which a sanctioning state claims jurisdiction. The four most common: settlement in its currency, passage through its financial institutions, incorporation of its technology, or participation by its nationals in the decision.

Dollar settlement is the broadest of them. A transaction entirely between third countries falls inside US jurisdiction once it is priced in dollars and cleared through the US system — neither party need ever have operated in the United States. This is extraterritorial jurisdiction in practice.

None of these hooks is about who the buyer is. They are infrastructure: currency, clearing, technology, insurance. A company can choose its customers; it cannot easily choose not to use dollars, not to use the London insurance market, not to use parts containing American technology.

Why are secondary sanctions more effective than primary ones?

Primary sanctions prohibit a state’s own persons from dealing with a target. Secondary sanctions impose consequences on third-country firms that deal with the target — usually by listing them too, or cutting their access to the sanctioning state’s market and financial system.

The difference is that this hands the choice to a third party. A Singapore trader breaches no law of its own; it simply has to decide whether to keep the trade or keep its dollar clearing. Most choose the latter, and that choice requires no enforcement at all.

The real force of secondary sanctions is therefore not punishment but expectation. Firms that withdraw pre-emptively far outnumber those actually penalised — and the former appear in no statistic.

Few are penalised, many withdraw — and only the top two layers are counted

Firms actually penalisedOn the record, countable
Fines, settlements, prosecutions. This layer has coverage, numbers, and case-by-case tracking — which is why it gets used as the measure of effect. It is the smallest part of the effect.
Third-country firms added to a listOn the record, countable
They broke no law of their own, and were listed for dealing with a target. Also visible — and its real function is demonstrative, aimed at everyone not yet listed.
Banks and insurers withdrawing on their ownUnannounced, but the client knows
The letter of credit does not issue, the cover is not written, the carrier declines. No regulator ordered any of it; each party simply avoided its own licence risk — and the trade fails all the same.
Firms withdrawing after assessmentNo record at all
Legal review concludes the risk is not worth it, so the contract is not renewed, the bid not made, the customer not taken. The decision is never announced and appears in no dataset.
Never attempted in the first placeNo record at all
The market never entered the plan. This is the largest layer, and even those inside it do not count it as an effect of sanctions — it has become the industry’s default.

On the record and countableUnannounced, known to those involvedNo record at all

The force of secondary sanctions lies in expectation rather than punishment. They hand the choice to a third party: a third-country firm breaks no law of its own and simply decides whether to keep the trade or keep its access to clearing and insurance. Most keep the access, and that choice requires no enforcement.

Measuring the effect by counting penalties therefore understates it badly. Only the top two layers leave a record, while the volume sits in the three below — and those in the bottom layer do not even register it as an effect. This is also the usual source of the argument about whether sanctions “work”: the two sides are looking at different layers of the same thing.

How does the sanctioned side work around them?

Every workaround aims at the same thing: removing the hook. Settle in another currency, change the flag and the insurer, route through a third-country entity, process the raw material into a different product before export.

The shadow fleet is the concrete case: ageing tankers, frequently changed flags and owners, insurance of uncertain provenance, dedicated to moving restricted crude. What it evades is not a navy but the insurance and classification systems.

Each workaround has a price — higher freight, dearer cover, longer voyages, bigger discounts. So sanctions are rarely a question of whether they work, but of how much cost they add. The discount is itself the evidence that they still bite.

What does this mean for a Taiwanese company?

First, define the compliance perimeter by the hooks, not by where the offices are. The question to ask is what currency settles the trade, which banks it passes through, and whose technology it contains — not whether you have a presence there.

Second, follow the end user downstream. Sanctions and export controls share a difficulty: most firms can see only their first-tier customer, while the test applies further down.

Third, banks and insurers withdraw before regulators act. A company usually learns of the problem not from an agency notice but from a letter of credit that will not issue and cover that will not be written. That is not economic coercion; it is the sum of many parties hedging separately — though the outcome is the same for whoever is caught in it.

Terms used here

Secondary Sanctions — Sanctions imposed on third parties for dealing with a sanctioned entity. The purpose is not to punish a specific transaction but to produce a chilling effect: global financial institutions, protecting their access to dollar clearing, pre-emptively avoid anything that might touch the target. In practice the enforcement power comes from bank risk aversion rather than from regulators' investigative capacity.
Economic Coercion — Using trade, investment, or market access as leverage to force concessions on non-economic issues. The signature methods are deliberately deniable: quarantine standards abruptly tightened, customs procedures inexplicably slowed, tour groups cancelled — none formally acknowledged as retaliation. That deniability is the design; it denies the target a justiciable dispute at the WTO or elsewhere.
Extraterritorial Jurisdiction — A state applying its law to conduct occurring abroad, typically hooked to settlement in its currency, the presence of its technology in a product, or use of its financial and information infrastructure. For companies this means that not operating in a market is no defence against its law — compliance scope has to be determined by the origin of technology and payment flows, not by where operations sit.
Shadow Fleet — Ageing tanker fleets operated to evade sanctions, characterized by frequent flag and name changes, disabled AIS transponders, ship-to-ship transfers on the high seas, and opaque insurance. They generate two distinct risks at once: a gap in sanctions enforcement, and the prospect of an uninsured elderly vessel causing an environmental incident in sensitive waters.
